To all whom it may concern: Be it known that ILNEILS A; NEILsEma citizenof the United States, and resident of Cupertino, in the county of SantaClara and tate of California, have invented certain new and usefulImprovementsin Gap-Closing 1v achines, of which the following is aspecification.

My. invention'relates to a'machine par- 7 ticularly adapted for fillingg'apsin earth ridges formed for irrigating purposes. I

It is the object of my inventionto provide a device of the characterindicated in which 7 ing with the same for automatically locking thepivoted bottom' 'after a dumping op-.

eration.

Fig. 3 is a rear elevation of'my invention.

Fig. 4 is a detail of a portion of the bottom locking and trippingme'chanismin operative position with relation to the draft mechanism.

Fig. 5 is a diagrammatical illustration of a portion of intersectingridges showing gaps to be closed.

Fig. 6 is a diagrammatical illustration showing the operation of thedevice.

Referring more particularly to the drawing, 1 1 indicates the two sidesof the. device and 2 indicates the back of the same,

of suitable size and form and secured at thein the position shownby-pins let extending through the openings 15 in the sides 1 just abovethe bottom 12and forward of pivots Application filed June 28, 1920;Serial No. 332,315.

spring 26 serves to normally hold pin 17 13 and carried on theloweriends of springs v16 secured to sides 1. A third pin is shown at 17extending through orifice 18 in the back 2 and just above the rear endofbottom 12. This pin 17. is carried by bar 19 provided witiha shoulder.at 20 and piv-' oted at 21 to a bracket 22 mounted on back 2 of thedevice.

Abar is shown upper end of bracket 22 andpivoted at its 1 shown at 25. Aspring 26 is'insertedback of this joint and mounted on back ,2 as

shown. Theupper end of bar123 is provided with an eye 27 to engage rod11 oniwhich it is held by'means. ofnut v28.v An adjustable stop is shownat 29 slidably mounted on rod 11 and fastened by set screw 30. The

In irrigating orchards by the check or and'eye Y flooding system, asuitable implement, is used to throwup a series of parallel ridgesextending from one side of the orchard to the other. To form the squaresor basins to receive the water it isnecessary to form another series ofparallel ridges extending at right angles to the first series. "In-doingthis, however, the ridging machine necessarily cutsthrough theridgesfirst formed thereby forming gaps therein'as at. 31, the

" formed afterward and crosswise of the first.

' To close these gaps so that each check or square will retain the waterturned therein ..1s a vgreat task when done by hand on an orchard ofmany acres asit is customary to form a square of ridged land about everytree. By means of the device herein described the labor. is reduced to aminimum and the gaps are quickly filled with but little effort on thepart of the single opera-- tor of themachine as he has merely to liftupwardlya little on handles 5 to effect the withdrawal of pin 17 asdescribed. Upon withdrawing pin 17; the' forward edge of bottom 1engages the ground and the whole structure moves iforward over the earthdumped by the'turning of bottom 12 as shownin Fig. 6, the said bottom 12making a co'mplete'half turn to be stopped by pinl? to pickup a newload.

In the present case pins 1a are rounded upontheir upper edgesto permitbottom 12 to slide easily thereover, but arefiat on their under sides tosquarely engage thesaid bottom 12 and direction. 7 v

It is to be understood of course that changes in details of constructionand method of operation may be made. within the scope of the appendedclaims.
